Why did researchers tighten the cap for temperature increase above pre-industrial revolution from 2 to 1.5 degrees? What additional threats did they realize will happen and how much more severe an impact would be?
Before we onboard on a journey to discover these, let’s make one thing clear – changes that each half a degree brings globally are not linear. After a threshold, they happen exponentially. Changes also will not affect everyone equally, some communities will suffer more than others.
